Pick 28-31
or
Pick 47-51 & B Prospect
Especially in a weak draft, there's really not a lot of difference between those two offers. The Coyotes might actually prefer the 2nd offer, if they think the B prospect can help Tucson in the playoffs.
If there's an offer from a team 1st or 2nd in the conference, they probably need to offer the conditional 1st to beat out a team further down in the standings offering a 2nd + B prospect. Until other teams start looking like sellers, AZ might be able to pull the conditional 1st from someone.
It should also be pointed out that Stone came back from injury to start the season. Some were saying he wouldn't be recovered in time for the season opener. So looking at his stats this season doesn't really tell the story. The 1st 20 games it was clear there was some rust and he was working to get up to speed. He's looking more and more close to his old form the last couple of games. If that holds true while pro scouts look at him over the next 5 weeks, his value is closer to the 1st.
